One way you will not get help is by posting the same question multiple times. If people aren't responding, maybe you've phrased your question wrong.
What have you tried so far? What problems have you hit? Unless you're *very* lucky, people won't spoon-feed you answers. AFAIK, the more you try and help yourself, the more helpful others are willing to be.
As for JWebUnit, have you read the "Quick Start" document? It covers the basics, including the areas you've asked about.
